This extremely fast object is not a nearby bird or insect. Clearly not a plane and no signs of a computer-generated effect. Graded B.
So why exactly is this not an insect?
I don't get it: I've watched the entire video, twice, but I can't find any flying disk. The only thing appears to be bugs, with a doozy close to the camera at 2:16 (repeated at 2:36).
